Illuminating Siderophore Transporter Functionality with Thiopeptide Antibiotics

mBio, 2023
The Gram-negative opportunistic pathogen Pseudomonas aeruginosa is a leading cause of infections and mortality in immunocompromised patients. This organism can overcome iron deprivation during infection via the synthesis of two iron-chelating ...

Pyoverdine production

, 2018
Pyoverdine production of isolates sampled from cystic fibrosis patients. For each sample is given: the Patient ID, the clone type, the absolute pyoverdine production as RFU/OD, the sample location, the length of infection of the clone type and overall in

Engineering siderophore production in Pseudomonas to improve asbestos weathering

Microbial Biotechnology, 2022
Summary Iron plays a key role in microbial metabolism and bacteria have developed multiple siderophore‐driven mechanisms due to its poor bioavailability for organisms in the environment.

Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa

BMC Microbiology, 2022
Background Iron is essential for almost all bacterial pathogens and consequently it is actively withheld by their hosts. However, the production of extracellular siderophores enables iron sequestration by pathogens, increasing their virulence.

Two new siderophores produced by Pseudomonas sp. NCIMB 10586: The anti-oomycete non-ribosomal peptide synthetase-dependent mupirochelin and the NRPS-independent triabactin

Frontiers in Microbiology, 2023
IntroductionGlobisporangium ultimum is an oomycetal pathogen causing damping-off on over 300 different plant hosts. Currently, as for many phytopathogens, its control relies in the use of chemicals with negative impact on health and ecosystems. Therefore,

Pseudomonas aeruginosa AlgR Phosphorylation Status Differentially Regulates Pyocyanin and Pyoverdine Production

mBio, 2018
Pseudomonas aeruginosa employs numerous, complex regulatory elements to control expression of its many virulence systems. The P. aeruginosa AlgZR two-component regulatory system controls the expression of several crucial virulence phenotypes. We recently

A compensatory RNase E variation increases Iron Piracy and Virulence in multidrug-resistant Pseudomonas aeruginosa during Macrophage infection.

PLoS Pathogens, 2023
During chronic cystic fibrosis (CF) infections, evolved Pseudomonas aeruginosa antibiotic resistance is linked to increased pulmonary exacerbations, decreased lung function, and hospitalizations.

A sensitive fluorescent biosensor for the detection of copper ion inspired by biological recognition element pyoverdine

, 2016
The environmental copper pollution seriously threatens the health of organisms and the safety of ecosystem. Therefore, the development of a simple and sensitive method to detect copper ion is very important. In this study, we have developed a fluorescent
